Moved project home to github.com/plainbook-ai/plainbook

[Luca de Alfaro]

Hi All, 

I did not like that plainbook resided under my personal name, so I created a plainbook-ai project (plainbook name seems reserved somehow as a project on GitHub) and moved the repository to there.   Github should be able to forward things, so I don't think this broke anything, but it may be better in the long run that you do this in your repositories to point to the new location: 

git remote set-url origin g...@github.com:plainbook-ai/plainbook.git

And in the snapshot-kernel one: 

git remote set-url origin g...@github.com:plainbook-ai/snapshot-kernel.git

I hope I haven't broken anything in the process...
